pose the merchandise or other articles carried thereby in an elevatedand out of the way position. I e

The invention aims to provide novel means for raising and lowering thesupport and to provide novel means for holding the support in adiustedvertical positions. i

It is within the scope of the .disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view. which will appear as thedescription pro-- ceeds, the invention resides in the combina tion andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within Y thescope of what is claimed. without departing from the spirit of theinvention.

In the accompanying drawing: Figure 1 shows'the invention in s1deelevation, parts being broken away; Fig. 2 is a cross section on theline 2-2 of Fig. 1; Fig. 3;is a cross section on the line 33 of Fig. 1.e c

In carrying out the present invention there is provided a lateralsupport 1 which may be the wall of a building, an overhead support 2being shown, the latter ordinarily constituting the ceiling. There isshown a vertical track 3 in the form of a rod or bar, ay b Wide enoughto receive the wheel 21. 100 the same, if desired, being provided at itsPivotally connected at 30 with the arm 10 ends with angularly disposedlegs 4 termi in front of the track 3 is a clevis 29. A pulnating in feet5 bearing against the lateral ley block 31 is piv ally connected asshown support 1 the fe t5 b ing tt h d t th at 32 with the overheadsupport 2. One end support 1 by means of securing elements 6 of aflexible element 33 is secured to the of any desired form. The track 3is pr clevis 29, the other end of the flexible element vided at pointsintermediate its ends with being carried upwardly through the pulleycontinuous, circumscribing shoulders denoted block 31 and thence beingextended downrespectively by the reference characters 7 wardly asclearly shown in Fig. 1 0f the and 8. drawings, .1 0

Mounted to reciprocate vertically on the track 3-is a frame denotedgenerally by the numeral 9. The frame 9 is a composite structure andcomprises a horizontally disposed upper arm 10, the rear end of whichterminates in bifurcations 11 ordinarily constituting a part of an eye12 surrounding the track 3. Mounted in the bifurcations 11 of Thebifurcations 18 which are formed at' the lower end of the brace 16support a pivot element 22 on which is fulcrumed intermediate its ends adog 23, the lower end of which is curved toward the track'3 and isadapted to cooperate therewith and, more specifically, cooperate withthe shoulders 7 and 8. The upper end of the dog 23 terminates in an arm24, extended rearwardly to a point beyond the track 3, the upper end ofthe dog 23 being offset as clearly shown at 27,

in Fig. 3, so that the extension or arm 24: may clear the track 3.Secured to the rear element 25 whereby the dog may be actuated. Aretractile spring 26 connects the upper end of the dog 23 with the brace16. The bifurcations 18 at, the lower end of the bracelG dog 23 cannothave a movement longitudinally of the pivot element 22 and becomeaccidentally disengaged from the shoulder 7 or the shoulder 8, theconstruction above described being such that, however, the eye19 7 endof the arm 24 of the dog is a depending p are contracted as shown at 28,so that the r that so soon as a pull upon In Fig. l of the drawings,the'frame 9 is shown in its elevated positiornthe lower end of the dog23 being engaged with the shoulder 7. When it is desired to lower theframe 9, the flexible element is pulled upon, the dog 23 tilting on itsfulcrum 22'," and the spring 26 being put under tension.

Thereupon, the frame 9 may be lowered, the

flexible element 33 being eased away and be ing paid out through thepulley block 31. When the, frame 9 is in its lowermost position, thelower end'ofthe dog 23 engages with the lower shoulder 8, 'it beingnoted the flexible element 25 is released, the spring 26 will react andwill swing the lower. end of the dog 23 inwardly so that the same bearsagainst the periphery of the track 3, the lower end of the dogultimately coming into contact with the shoulder 8 as the frame islowered. Owing to the fact that the shoulders 7 and 8 extend entirelyaround the track 3, the frame 9'rnay be swung horizontally withoutcausing a disengagement of the lower end of the dog 23 from eitherot theshoulders. The wheels 15 and 21 serve to guide theiframe 9 in itsvertical movement along the track 3 and LCilitate such movement. Owingto the fact that thedog 23 is provided at its upper end with arearwardly extended arm 24 which projects beyond the track 3, theflexible element 25 which controlsthe dog is always eX- posed and is notencumhered by articles of any. sort which maybe suspended from thearmlQ.

Having thus described the invention, what is claimed is 7 V I 1. In adevice of the class described, an upright track; a frame mounted toreciprocate on the track; an upright dog pivotally mounted on, the frameand including a rearwardly extended arm disposed transversely of thetrack; a depending operating element 7 connected to the rear end of thearm; and a retraetile spring forming a connection between the-dog andthe frame, the spring constituting means for maintaining the dog engagedwith'the track, and the track having a shoulder with which the dog isadapted to coact.

2. In a device of the class described, an upright track; a framecomprising an upper arm, a lower arm and a brace connecting thearms;a'wheel journaled for rotation on the upper arm and engaging oneedge of the track; a wheel journaled for rotation on the lower arm andengaging the opposite edge of the track; and a movable dog carried bythe lower arm, the track having a shoulder with which thedog is adaptedto cooperate.

3. Ina device of the class described, an upright track provided with acircumscribing shoulder; a frame mounted to slide longitudinally on thetrack and to rotatetransversely of the track; a dog pivotally carried bythe frame and adapted to coact with the shoulder; and spring meansoperatively con meeting the dog with the frame and constituting meanswhereby the dog will be maintained in engagement with the track prior tothe engagement with the dog and the shoulder,the dog being adapted tomaintain its engagement with the shoulder under the actuation of thespring, when the frame is rotated transversely of the track.

at. In a device of the class described, an upright track; a framecomprising upper and lower arms. and a brace connecting the arms, thearms receiving the track slidably; a dog fulcrumed intermediate its endson the lower arm and having at its upper end a rear ward extensionprolonged beyond the track; depending actuating means connected with therear end of the extension; a retractile spring forming a connectionbetween the dog and the brace,'the lower end of the dog being adapted tocoact with the track, and the track having a shoulder with which the dogis adapted to cooperate.

In testimony: that I claim the foregoing as my own, I have heretoaiiixed my signature in thepresence of two witnesses.
